Please let me know if anyone has any advice on hardwood installed on a concrete slab. We're planning on doing the work ourselves and performing the install using a quality underlayment and wondered whether or not it is warranted to perform a moisture analysis on the concrete slab which was poured years ago and is in perfect condition without any cracks or wear. Also, if we should perform a moisture analysis, please recommend any kits or systems with which to perform that analysis. Thanks very much, any help is greatly appreciated!

The industry standard is still the CC test. You MUST follow the instructions to the letter.

If you can obtain a Tramex Moisture Encounter, that will work quite well also. Your best bet maybe to hire someone to perform either of these moisture tests. IF you go with a floating floor, you could forgo testing altogether. WHY? Because you would cover the entire slab and drap up the walls a few inches with 6 mil polyethylene. Once covered properly, no moisture vapor from concrete will penetrate this barrier. Over that, a quality foam pad/underlayment is placed ( The Floor Muffler is a good one ). Then the wood flooring is installed/floated over that. This is a simple yet effective system for concrete slab subfloors and is good for DIYers because of it's simplicity and there is no need for many specialty tools or expensive adhesives.

I'm with Gary on that one. I use six mil under all 2&1 vapor barrier/cushions these days just for that extra insurance as I've seen some cheaper ones allow mositure through.
